As far as I know (and I the physical issues to prove it), PC Gamer didn't begin numbering their CDs until #150, July 2006. The June 2006 issue had the key #7.67 on both the disc and the magazine's spine.
I own the physical magazine and CD, and it only came with 1 disc, not two. I think that perhaps this discs are from another month.
So, if anyone can scan the sleeve or their discs to clarify this matter, it would really help us all here.
